Tobacco 21 (T21) policies raise the minimum legal age to purchase tobacco from 18 to 21 years to curb youth access to tobacco products. While some studies have found that T21 is associated with reducing prevalence of youth tobacco use, little is known about the impact it may have on youth of different racial and ethnic identities.
To evaluate the association of T21 policy with the prevalence of high school youth tobacco use across sex, race, and ethnicity.
DESIGN, SETTING, AND PARTICIPANTS: This survey study used representative survey data collected from the local biennial Youth Risk Behavior Survey from 2013 to 2017 comparing Cleveland, Ohio (which has a T21 policy), to proximal jurisdictions in the first-ring suburbs in Cuyahoga County (which do not have T21 policies). Within-Cleveland demographic information was also collected for 2013 to 2019. Overall high school youth tobacco use rates were compared between Cleveland and the first-ring suburbs and then examined within Cleveland among Hispanic, non-Hispanic Black, and non-Hispanic White high school students. Percentage data were adjusted to more closely align with local population demographics. Data were analyzed from January to June 2022.
T21 was implemented in Cleveland in 2016 and not adopted in proximal jurisdictions or at the state and federal level until at least 1 year later.
The main outcomes were prevalence of past 30-day cigarette, cigar product, or e-cigarette use, measured using geographically representative high school youth survey data from 2013 to 2015 (prelegislation) and 2017 to 2019 (postlegislation) and compared using a difference-in-differences analysis.
The unweighted sample included 12 616 high school students (27.0% [95% CI, 26.9%-28.0%] in 10th grade; 50.9% [95% CI, 50.3%-51.6%] females) participating in 1 or more Youth Risk Behavior Surveys from 2013 to 2019, including 7064 students in Cleveland and 5552 students in the first-ring suburbs. Compared with the first-ring suburbs, Cleveland had a greater proportion of younger students (1623 [28.5%] ninth grade students vs 2179 [34.0%] ninth grade students) and Hispanic students (436 students [1.1%] vs 1433 students [12.6%]) and non-Hispanic Black students (2000 students [53.1%] vs 3971 students [75.1%]). Cigars were the most commonly used tobacco product in Cleveland, with use reported by 6201 students (19.8%) in 2013, 5877 students (21.3%) in 2015, and 5784 students (16.8%) in 2019. Compared with the first-ring suburbs, there was a greater decline in prevalence of use of cigars in Cleveland (β = 0.18 [SE, 0.05]; P < .001). The disparity across race, ethnicity, and sex decreased for all current tobacco product use. For example, the maximum difference between demographic subpopulations in current cigarette use was 11.6 (95% CI, 9.5-13.7) percentage points in 2013 between White females (16.1% [95% CI, 11.3%-20.8%]) and Black males (4.5% [95% CI, 3.5%-5.4%]). This maximum difference in current cigarette use decreased significantly to 5.1 (95% CI, 3.5-6.7) percentage points in 2019 between White females (6.9% [95% CI, 3.4%-10.3%]) and Black females (1.8% [95% CI, 0.7%-2.8%]).
This survey study found that there was a decline in youth-reported tobacco use across every tobacco product category from 2013 to 2019. This decline changed the trajectory of use among several demographic groups and brought the youth populations with the highest tobacco product use to similar rates of others.
重要性:烟草 21 (T21)政策将购买烟草的最低法定年龄从 18 岁提高到 21 岁,以遏制年轻人接触烟草产品。虽然一些研究发现 T21 与减少青少年烟草使用的流行率有关,但对于不同种族和族裔的年轻人可能产生的影响知之甚少。
目的:评估 T21 政策与高中青少年烟草使用流行率之间的关联,考虑到性别、种族和族裔的差异。
设计、地点和参与者:这项调查研究使用了代表克利夫兰市(俄亥俄州)和凯霍加县第一环郊区(没有 T21 政策)的当地每两年一次的青年风险行为调查的数据,比较了 2013 年至 2017 年的数据。克利夫兰市的内部人口统计数据也从 2013 年到 2019 年进行了收集。比较了克利夫兰市和第一环郊区的整体高中青少年烟草使用率,然后在克利夫兰市的西班牙裔、非西班牙裔黑人和非西班牙裔白人高中生中进行了调查。百分比数据进行了调整,以更紧密地与当地人口统计数据保持一致。数据于 2022 年 1 月至 6 月进行分析。
暴露情况:T21 于 2016 年在克利夫兰市实施,至少在一年后才在毗邻的司法管辖区或州和联邦一级采用。
主要结果和措施:主要结果是过去 30 天内吸烟、雪茄产品或电子烟使用的流行率,使用具有地理代表性的高中青少年调查数据进行衡量,数据来自 2013 年至 2015 年(立法前)和 2017 年至 2019 年(立法后),并使用差异差异分析进行比较。
结果:未加权样本包括 12616 名高中生(第 10 年级 27.0% [95% CI,26.9%-28.0%];50.9% [95% CI,50.3%-51.6%]为女性),他们参加了 2013 年至 2019 年期间的 1 次或多次青年风险行为调查,包括克利夫兰市的 7064 名学生和第一环郊区的 5552 名学生。与第一环郊区相比,克利夫兰市有更大比例的低年级学生(1623 名 [28.5%] 为 9 年级学生,而 2179 名 [34.0%] 为 9 年级学生)和西班牙裔学生(436 名 [1.1%],而 1433 名 [12.6%] 为西班牙裔学生)和非西班牙裔黑人学生(2000 名 [53.1%],而 3971 名 [75.1%])。雪茄是克利夫兰市最常使用的烟草产品,2013 年有 6201 名学生(19.8%)报告使用,2015 年有 5877 名学生(21.3%)报告使用,2019 年有 5784 名学生(16.8%)报告使用。与第一环郊区相比,克利夫兰市的雪茄使用流行率下降幅度更大(β=0.18 [SE,0.05];P<0.001)。所有当前烟草产品使用的种族、族裔和性别差异都有所缩小。例如,在 2013 年,白人女性(16.1% [95% CI,11.3%-20.8%])和黑人男性(4.5% [95% CI,3.5%-5.4%])之间的当前香烟使用的最大差异是 11.6(95% CI,9.5-13.7)个百分点,这是所有人口统计学亚群之间的差异。这一最大差异在 2019 年显著下降至 5.1(95% CI,3.5-6.7)个百分点,当时白人女性(6.9% [95% CI,3.4%-10.3%])和黑人女性(1.8% [95% CI,0.7%-2.8%])之间的差异。
结论:这项调查研究发现,从 2013 年到 2019 年,青少年报告的烟草使用在每一种烟草产品类别中都有所下降。这种下降改变了几个人口群体的使用轨迹,并使使用烟草产品最多的年轻人与其他人的使用率相近。
